Many of which were made with the new 40mm XS lens. View and judge yourself on the IQ and characteristics. Colour saturation seems a bit too high to my like and maybe this is the root cause of the colour cast in many of the K-01 photos that I've seen so far. Large images are available but they are yet not full sized.
